I am undecided, but when weighing it up to me it seems like he will do a repeat of his 2011 season and if he does not.. well he is still bound to at least equal his points..

He is very likely going to be the Boonen of next year..

This year he entered the season on a new team, after a season where he dominated everything (probably felt some fatigue after 2011), A virus was sweeping through the BMC team (Evans, Hushovd effected, can't remember if Gilbert was or wasn't), and his priorities were focused more towards the later part of the season.
I don't think he will have those problems in 2013, plus he finally has the rainbow jersey that he has been after for so long, so he will want to do it proud and will get in good form for the Ardennes and others races. He won't be as dominating as 2011 but he will still be very good I think.

I think he will score 2000 points max so Alberto is a better pick.

The great Alberto Contador

Personally at this point I see Gilbert as the more likely of the two to score a lot of points. Plus Contador is around 200 points more, and when your trying to fill up your roster with 33 riders every point counts. I could see Gilbert scoring anywhere between 2000 to 2500 points. Maybe if Contador was known to be riding more than one GT I would say he could score more but at this point it's not even known if his team will get a licence.
